Frontier use rates, by either soil CEC values or by soil texture and organ;c matter, are given in specific crop use sections of this label. When use rates are expressed in ranges use the lower end of the rate range for lower CEC values and use the higher end of the rate range for higher CEC values. If texture and organic matter are used to determine 'Jse rates, use the lower end of the rate range for more coarsely textured soils low in organic matter and the higher end of the rate range for more finely textured soils that are high in organic matter.

8 20 Jun. 1984

FRONTIER HERBICIDE USE METHODS AND TIMINGS

frontier may be applied preplant surface. pre plant incorporated. preemergence or early postemergence to field corn, seed corn, popcorn, and soybeans.

Best weed control will result when applied (by ground or aerial equipment), and subsequently incorporated into soil by rainfall. sprinkler irrigation. or mechanical tillage prior to weed seedling emergence from soil.

PREPLANT SURFACE APPLICATIONS

) For use in minimum tillage or no-tillage production systems. application of Frontier alone or in tank mixtures may be made up to 45 days before planting. When m;,king early preplant applications (15 to 45 days prior to planting) use the highest rate recommended for the specific soil type. Early pre plant applications are not recommended for use on coarse textured soils or in areas where average annual rainfall (or rainfall + irrigation) typically exceeds 40 inches. Early preplant applications mat be applied as part of a split application program where the second application is made after planting (use 2/3 of Frontier rate early followed by 1/3 of rate after planting). A split application is recommended when initial application is made more than 30 days prior to planting. Tank mixtures with postemergence herbicides such as Roundup'" or Gramoxone Extra'" must be used when weeds are present at the time of application.

PREPlANT INCORPORATED APPLICATIONS

Apply Frontier and incorporate into the upper (1-2 inch) soil surface up to two weeks before planting. Use a harrow. rolling cultivator. finishing disk. or other implement capable of giving uniform shallow

) incorporation. Avoid deeper incorporation or reduced weed control andlor crop in;ury may result.

PREEMERGENCE SURFACE APPLICATIONS

Broadcast treatment uniformly to the soil surface after planting and before crop emergence. Rainfall. sprinkler irrigation. or sl:lallow mechanical incorporation aftllr application is required to move this ,,/ product into the upper soil surface where weed seeds germinate. If IIdequate rainfllll or irrigation does not occur and weed seedling emergence begins. a shallow cultiv

MIXING OF SPRAY SOLUTIONS

18 20 Juno 1994

Frontier is a concentrated liquid herbicide that can be mixed for application in water. sprayable fluid fertilizer. or it may be impregnated on dry bulk fertilizer. When herbicide tank mixtures or mixtures with sprayable fluid fertilizer are to be used. a compatibility test should be conducted prior to tank mixing (SEE COMPATIBILITY TEST section in this label).

When loading a spray tank for application of Frontier (alone or in tank mixtures with other products) use the following order for mixing:

1. Thoroughly clean spray tank prior to use. 2. Fill sprayer tank one-half full of either water or sprayable fluid fertilizer. 3. Start sprayer agitation system and continue agitating throughout mixing and application. 4. If compatibility test indicated the need for addition of a compatibility agent. add the amount

recommended on the label of the selected compatibility agent. j 5. If tank mixing with wettable powder or dry flowable products. make a slurry of these products

with water and add slowly to spray tank. 6. If tank mixing with a flowable formulation. add this product slowly to spray tank. 7. Add Frontier herbicide to spray tenk. 8. If tank mixing with emulsifiable concentrates or soluble liquid products add these products to

spray tank. 9. If tank mixing with Gramoxone Extra or Roundup add these products as rem~inder of spray

tank is filled with carrier. 10. If adding spray adjuvants. add them after all other products have been mixed.

GROUND or AERIAL APPLICATIONS

Apply the recommended rates of Frontier in 2 or more gallons of spray solution per acre. AchJal minimum spray volume per acre is determined by spray equipment used for application. Application must be made in adequate volume to provide accurate and uniform distribution of spray particles over treated area and to avoid drift of spray particles to non-target areas. In addition. when Frontier is used in tank mixtures. spray volume used must be no l£s5 than the minimum volume required by the tank mix product. Use nozzle screens no finer than 50 mesh when spraying tank mixtures with wettable powder or flowable formulations.

Row width per acre per acre in inches

Band width in inches X Broadcast Volume = Band Volume

Row width per acre per acre in inches

USE OF SPRAY ADJUVANTS

Frontier is a preemergence herbicide for which spray adjuvants have little or no influence on performance. However, several herbicides used in tank mixtures with Frontier require use of adjuvants to aid in the burndown of emerged weeds. Use only those adjuvants cleared for agric'Jltural crop use. Surfactants and/or low rate fertilizer (28%, 30% or 32% UAN or ammonium sulfate) adjuvants may be used with tank mixes applied preplant, preemergence or early postemergence to the crop. Crop oil concentrates may be used prior to crop emergence but are not recommended after crop emergence unless specified for a particular tank mixture.

COMPATIBILITY TESTING

A ccmpatibility test is recommended for applications with liquid fertilizer. Before mixing products / in the spray tank, small amounts of all products can be mixed in proportionate quantities to determinr compdtibilities. The amounts of carrier and products in this compatibility test are based on a spray volumE! of 25 gallons per acre. Make appropriate changes in amounts for your specific spray volume.

To conduct this test begin by adding one pint of the liquid fertilizer solution to a one quart container. Then add, in sequence as given above, 1/2 level teaspoons per lb. use rate for dry formulated products and 1/2 teaspoon per pint( 16 fluid ounces) use rate of liquid formulated products. Agitate materials by covering and gently shaking container for 5 to 10 seconds between each product addition.

If herbicide(s) do not ball-up or form flakes, gels, sludge, oily film or layers, or other precipitates, then the tested spray mix is compatible. Incompatibility in any of the above described forms will normally occur within 5 minutes after mixing. If components are incompatible, the use of a compatibility agent is recommended.

Rerun the above compatibility test with a suitable compatibility agent (114 teaspoon in test is equivalent to a use rate of 2 pints per 100 gallons of spray volume). If the mixture is then compatible, use the compatibility agent as directed on its label. If the mixture is still incompatible, the liquid fertilizer and herbicide(s) should not be mixed for use in the same spray tank.

DRY BULK FERTILIZER APPLICATIONS

20 20 Juno 1994

Frontier may be impregnated or coated onto dry bulk granular fertilizer carriers fOl preplant surface, preplant incOlporated or preemergence applications. may be conducted by either the bulk 01 the on-board sYlltelm

Frnnti'~r may - registered for these application systems. Individuals or agents selling Frontier in these application

systems are responsible for fc'Il)wing allstate and local regulations regarding fertilizerlherbicide blending.

Addition of a drying agent may he necessary if the fertilizerlherbicide blend is too wet fOl uniform application due to high humidity, high urea concentration, and/or low fertilizer use rate. Slowly add the drying agent to the blend until a flowable mixture is obtained. Drying agents are not recommended for use with on-board impregnation systems.

Under some conditions fertilizer impregnated with Frontier may clog air tubes or deflector plates 011 pneumatic application sY5tems. Mineral oil may be added to Fronticr before blending with fertilizer to reduce plugging. Do not use drying agents when mineral oil is used. To avoid separation of Frontier and mineral oil mixes in cold temperatures either keep mixture heated or agitated prior to blending with fertilizer. Mineral oil may be used at in-plant blending stations or on-board injection systems.

Apply 200 to 750 pounds of fertilizerlherbicide blend per acre. Application must be made uniformly to the soil to prevent possible crop injury ar.d offer satisfactory Wiled control. Impregnated fertilizer J spread at half rate and overlapped to obtain a full rate will offer a more uniform distribution. A V shallow (1-2 inch) il". Jrporation is desirable for improved weed control. Deeper incorporation may result in unsatisfactory weed control. /

Formula to determine herbicide ratels):

INCOMPATIBLE MIXTURES - DO NOT impregnate Frontier or Frontier mixes on ammonium nitrate, potassium nitrate, or sodium nitrate fertilizers or fertilizer blends. Single superphosphate (0-20-0) and triple superphosphate (0-46-0) may be impregnated only with Frontier alone.

ROTATIONAL CROPS

If the corr. or soybean coop treated with Frontier is lost to adverse weather or for other reasons, the area treated may be replanted to corn or soybeans immediately. If the original Frontier treatment was bror-dcast do not make a second application of Frontier. If the original applic3tion was banded and
